To all whom it may concern.,

Be it known that I,'FRANZ j ect of the Emperor of Austria-Hungary, and

shaft machine also run solely through thea resident of New York, in the county and State of New York, have invented certain new and useful Improvements in Automobiles, of

which the following is a specification.

This invention relates to improvements in automobiles and particularly to improvements'in theaxle which is made of one piece and curved so that its outer ends alone are in connection with the wheels.

The principal objects of the invention are tojproducean automobile axle which may be used in connection with chain operated machines as well as with shaft'machines.

Each rear wheel turns on 'an end stump of chassis frame with the exception of the.

springs. Thus the chains and chain wheels are located within said frame and the whole chain mechanism is surroundedby a casing filled with oil so that the chain mechanism ,runs in oil and is protected from dust and other exterior influences. Theshafts. of the outer stumps of the axle, they end in the frame of the differential mechanism and arealso interrupted. By the use ofthe novel axle anyof the rear wheels may be taken directly off without disturbing any other part of the machine. All machine parts being within the chassis frame in chain oper-. ated machines the automobile looks like a private carriage and all parts arewell protected.

The novel construction of the axle brings forth a number of improvements of the parts in and on the hub which will be fully described further down.

'The invention further consists in the con struction and arran ement of the single parts comprisingthe mec anism. It is illustrated in the accompanying drawings in which:

Figure 1 represents in top lan view the. rear part of a' motor vehic emechanism' which embodies inu'desi-rable form and ar- .ran ement the present. improvements; asapp 1e d to a chain 0 erated mechanism. .1g. 2 illustrates m rear e evatlon the arrange- .ment of the axleand other parts as ap lied to a shaft machine. Fi 3 is a vertica sec.-

tion' of the mechanism %0 stump and shaft. Fig. 4 is a cross section on line 4, 4 of Fig. 3. Fig. 5 is a cross section on anism partly'broken away.

Similar characters of reference denote like parts in all the figures. In the drawings a represents the axle hubof a wheel. At the inner ends of the short pieces or stumps of the axle same forming the part a which is I. shaped in cross section. The axle is made of one piece out in order to receive each a shaft-6,1). f' The arrangement on both sides of the axle same. Therefore I shall describe the construction of this mechanism solelywith refin detail in Fig. 3.

mechanism and brake.- supported by a standard a which is riveted to the I shaped part a of the axle. The end section "of .whichis shown in Fig. 5.- The head of the shaft is considerably larger in dirests against the front end of the axle. A ring 0 is provided on the head of the shaft, it is cut out so as to closely fit the shape of the same. The shape of the shaft head and ring has been selected as shownso as to present a number of surfaces, eight are preferably transmitted to the I'lDg in a uniformimanner. Two holes b 6 areprovided in the shaft head in which atool is inserted whenthe the shaft forms a short stem b which; is threaded and-'adapted'to receive a-washer d and-a nutv e. On thetaxle thereis-an axle almost rectangular 1 pin which. extends cated' on one axle line 5, 5 of- Fig.3. Fig. 6 is a cross section. 'on line 6, 6 of- Fig. 3,'and Fig. 7 shows in' side elevation the casing for the chain mechand in connection with each wheel is the.

whose side ends (1 ,11 pass each through the if extend downward and horizontally across and all its parts are integral with each other. The" stumps a, a of the axle are hollowed ring 0 is to be-removed. At'the outer end i i nut f screwed to the-threaded front-.endof the same. This nut f iscutfout to receivean .1 down intothef-axle andla terbeing jnserted I 'isturnedso as to fullysecure said muatothe provided at the other side which is held in same.

position by a flange a of the shaft 0. The two ball bearings are further kept in position by a ring 7c located on the axle. The front end of the hub 1 is inside shaped as shown in Fig. 5 to fit the ring 0 whereby the hub is connected to the ring 0 and turns with The spokes m are secured in the hub and the two described ball bearings are lo cated on both sides of the spokes. Right behind the ball bearing 1' there is provided on the axle a seat 'a on which rests the spring n. Adjoining the spring nthere is a small ball bearing 0 on the shaft 1) and a like ball bearing p is located at the end of the shaft held in position by a nut As seen from Fig. 3 the ball bearin g is supported by a standard 0!, which is bo ted to the axle part a Between the ball bearings o'and p on the shaft 1) there is secured the chain mechanism 1 which is shown in detail in Fig. 7. The chain'mechanism itself is of usual construction and does not require any detailed deed the brake t which is of usual construction and operated in the usual manner.

The chain wheel r is secured on the shaft 1) while the chain wheel r is secured to a shaft a which is supported in the chassis frame 0 and runs into the casing :20 which contains the difierential mechanism. I 1

Y It is plainly seen that the described con struction and arrangement of the various parts composing the mechanism are very port the shafts y,

effective and practical because all the parts except the springs are located within the chassis frame by virtue of the described construction of the novel axle while in the present chain machines the chain mechanism is outside of the frame and can not be mounted within same. the frame and leaving a free space renders it possible to turn sharp corners without danger of. injuring the mechanism or breaking part-of same.

In; Fig. 2 the axle a, is shown as applied to a shaft machine, its end stumps likewise pass tlnough the hub of the wheels and sup- The shafts end within theihousing z of t e differential mechanism and also leaving a free space between ex- Another ball bearing i is The shafts b, b ending within' tending in the casing just far enough to connect thereon the differential mechanism. Thus the same style of shaft is applicable to both kinds of motor vehicle mechanisms, the chain operated one as well as the shaft machines.

The power engine 0 )erates the differential mechanism whereby the shafts u are turned rotating the chain wheels r from where the chains transmit the power to the chain wheels r revolving .each a shaft 1) whose head is connected with a ring 0 which is connected to the hub whereby the wheels are turned on the stationary axle. The arrangement of the two sets of ball hearings on each side, one set composed of two ball hearings on the axle and one set composed of two ball bearings on the shaft insure a perfectly smooth running of the vehicle.

In the described manner I have produced a motor vehicle which is highly effective and not liable to get easily out of order because all the parts composing the actuating mechanism are located within the chassis frame save the seat for the spring itself. This desirable arrangement is rendered possible by virtue of the novel construction of my improved stationary axle. Having thus described my invention I claim as new and desire to secure by Letters Patent 1. Amotor vehicle or automobile in which the actuating mechanism is located within the chassis frame comprising a drop axle with a stum on each end passing through the hub of a w eel, borings in said stumps, a wheel shaft in each boring, a ball bearing on each side of the wheel on the axle stump, a third ball bearing on each shaft at the end of each axle stump, a fourth ball bearing at the inner end of each shaft, and a standard bolted to the drop axle supporting the last named ball bearing and the inner end of the shaft.
